Limited Space High Performance Antennas
Unlike the usual trap antenna, there are no capacitors to break down under high RF voltages. 50 Ohm direct coax feed; tuner usually not required when operating in resonant bands, but may be used for multi-band.
Model DX-CC multi-band 80, 40, 20, 15 and 10 meter dipole
SEVERE WEATHER RATED
ALPHA DELTA MANUFACTURED ANTENNAS NOW MADE IN OUR IS0-9001 CERTIFIED PRODUCTION FACILITY.
DX-A - 160-80-40 Meter 1/4-wave Twin Sloper - A top low frequency DX antenna. Combines the tremendous DX firepower of the 1/4-wave sloper with the wide bandwidth of the 1/2-wave dipole. One leg is 67 ft., the other 55 ft. Installs like an Inverted-V with ground return accomplished thru tower or down-lead.
DX-B - 1/4-wave DX sloper - A single wire with high performance on 160, 80, 40 & 30 meters. Designed for limited space installations where room doesn't allow for the DX-A twin sloper. Requires only 60 ft. overall and provides amazing DX performance at installation heights of only 35 ft., and with the low end at only 8 ft. Pre-assembled & Pre-tuned. just put it up and start enjoying low band operation. Utilizes stainless-steel hardware, 12 gauge solid copper wire and efficient Alpha Delta "Iso-Res" RF choke coils. To gain the same broadbanded performance like the DX-A, the DX-B is also designed to be used with a wide range antenna tuner, so no trimming or tweaking is necessary. 50 Ohm coax feed, rated for full legal power.
The Models DX-A and DX-B quarter wave slopers require mounting on a grounded tower with an HF size beam on top to act as a "capacity hat". This is necessary for proper tuning and operation. This is not a requirement for half wave dipoles, but unique to quarter wave slopers for transmitting.
DX-SWL - SWL Broadcast Sloper - Covers the 13, 16, 19, 21, 25, 31, 41, 49, 60, 90, and 120M short-wave bands plus the AM broadcast band. Sloper design provides outstanding reception of low-angle DX signals. Multi-band 2KW transmit capability with an appropriate antenna tuner. Overall length is 60 ft.
DX-CC - No-Trap 80-40-20-15-10 meter dipole or inverted-V. Overall length is 82 ft.
DX-DD - No-Trap 80 and 40 meter dipole or inverted-V. Overall length is 82 ft.
DX-EE - No-Trap 40-20-15-10 meter dipole or inverted V. Also covers 30-17 & 12 meters with an antenna tuner. Overall length is 40 ft.
160M 20kHz 80M 40 kHz 40M 300 kHz
Full band coverage can be accomplished with an antenna tuner. Built with insulated 12ga. wire, stainless steel hardware and uses the Model DELTA-C static protected center insulator and CIN end insulators. Use coax or open wire line and configure as a dipole or inverted-V. Assembled and ready to go!
DX-ULTRA - Design and construction same as the Model DX-CC, but slightly retuned to favor HF shortwave.
DX-Series - Monoband Dipoles
Full-size dipoles utilizing the Delta-C Center Insulator with built-in Arc-Plug® Surge Suppressor. Fully assembled using 12 ga. insulated high-strength solid copper wire, CIN end insulators & 50 ft. nylon support rope. Feed with coaxial cable or open-line, rated for legal power.
